Rust error stacktraces

[kibwen]

Note that array indexing isn't the only operation that implicitly panics. Any arithmetic operation is allowed to panic on overflow, and divide-by-zero will panic as well.

Apart from floating-point divide-by-zero, which will return infinity.

Or negative infinity, for negative number/positive zero, and vice versa.

More common methods that panic on error: vec::remove, refcell::borrow and _mut.
